Title: Prolonged release of gm-csf
Inventor: LAWTER JAMES RONALD
IPC: A61K47/30
Filed: 1996-10-10
Abstract: Formulations for controlled, prolonged release of GM-CSF have been developed.  These are based on solid microparticles formed of the combination of biodegradable, synthetic polymers such as poly(lactic acid) (PLA), poly(glycolic acid) (PGA), and copolymers thereof with excipients and drug loadings that yield zero order or first order release, or multiphasic release over a period of approximately three to twenty-one days, preferably one week, when administered by injection. In the preferred embodiment, the microparticles are microspheres having diameters in the range of 10 to 60 microns, formed of a blend of PLGA  having different molecular weights, most preferably 6,000, 30,000 and 41,000. Other embodiments have been developed to alter the release kinetics or the manner in which the drug is distributed in vivo. For example, in some cases a polymer is selected which elicits a mild inflammatory reaction, for example, PLGA and polyanhydrides can act as chemoattractant, either due to the polymer itself or minor contaminants in the polymer, or polymers which are bioadhesive are used for transmucosal or oral delivery. In another embodiment, the GM-CSF is administered in a hydrogel which can be injected subcutaneous or at a specific site for controlled release. The microparticles or hydrogel are administered to the patient in an amount effective to stimulate proliferation of hematopoietic cells, especially white cells.

Title: A dynamically enhanced v-blender
Inventor: ROBINSON PRISCILLA A
IPC: B01F29/60
Filed: 1996-10-25
Abstract: A study was done to compare the performance of a conventional V-blender to a V-blender that incorporates perturbations of the particle flow by rocking the mixing vessel during its normal rotation. Mixing was investigated using glass beads with sizes from 66µ to 600µ in vessels of approximately one liter volume. Mixture uniformity was assessed qualitatively, using two different methods. One method involved a transparent mixing vessel where it was possible to see particle flow patterns and assess the state of the mixture at its surface during the entire experiment. The second method involved disposable aluminum mixing vessels, where the mixture was solidified by infiltrating the mixture with a binder. By slicing the solidified structure, it was possible to assess the entire state of the mixture including its interior structure after the completion of each experiment. Mixture uniformity was also assessed quantitatively using image analysis of the slices. For both particles sizes, the extent of mixing was greatly enhanced using the rocking V-blender compared to the conventional V-blender.

Patent CA-2239562-A1 (CA)
Title: Remote control receiver
Inventor: NAKANISHI YUTAKA
IPC: G08C19/28
Filed: 1998-06-26
Abstract: The back end position of a pulse, which is transmitted from a remote control, varies according to the transmission distance, and the pulse width changes. A remote control receiver of the present invention detects the pulse width of a header, which is formed at the head of each frame in a remote control signal from the remote control, so as to detect the transmission distance of the remote control signal and a change in back end position of each pulse in a data part, which is transmitted after the header. Then, the back end position of each pulse is corrected to original.      This eliminates the change in pulse width resulting from a change in transmission distance, and increases the allowable range of the transmission distance of the remote control.
Patent CA-2240473-A1 (CA)
Inventor: SHINE IAN BASIL
IPC: A61M5/172
Filed: 1996-12-27
Abstract: In a method of generating a clock signal having a desired frequency, a pulse is generated each time a stored accumulator value (tank) is found to be greater than or equal to a stored (trigger) value. In a first loop (10), the stored accumulator value tank is iteratively incremented by a first iterative value (r) until the stored accumulator value is greater than or equal to the stored trigger value and subsequently in a second loop (11) the stored accumulator value (tank) is decremented by a second iterative value until the stored accumulator value is less than the stored trigger value. During each iteration of the first loop (10), a current frequency of the clock signal is compared to a desired frequency value and if the two values are different, the first iterative value (r) is corrected at a predetermined rate (accRate) over one of more subsequent iterations until the frequency of the generator clock signal corresponds to the detected value of the desired frequency. In a preferred example, the number of iterations needed to change the first iterative value (r) is determined by a stored accumulator value which is added to an accelerator-accumulator (AccTank) for each iteration that the first iterative value and the desired frequency are not exactly equal.

Inventor: HARRIS GRANT T
IPC: H01B7/28
Filed: 1998-06-23
Abstract: A multiconductor electrical cable for use in a subterranean wellbore includes at least one electrical conductor surrounded by one or more layers of insulating material, such as EPDM. A fluid barrier, such as an extruded layer of lead or a lead alloy, surrounds the insulating material. To protect the fluid barrier from damage during the subsequent armoring process, a non-braided material is applied, as an extrusion or a tape. The non-braided material can be applied immediately after the fluid barrier is applied, not as a separate process, thereby reducing the risk of damage to the fragile fluid barrier, and at a cost less than the braided materials used in the past.
